It really is just console rotation, all other fb-based apps would still
display in the standard "upright" position unless specifically written
for display rotation, such as Xfbdev.

I'm not sure if the patch I submitted will even be accepted.  My point
is that it's easier to do this in the 2.5 fb framework than in 2.2-2.4. 
But you can already use Xfbdev in 2.4 to rotate the display.
